UNITED STATES PATENT OFFICE.

W. D. MAYFIELD, OF BLOOMINGTON, ILLINOIS, ASSIGNOR TO HIMSELF AND S. D. PORTER.

MODE OF DETACHING HORSES FROM VEHICLES.

Specification of Letters Patent No. 18,426, dated October 13, 1857.

To all whom it may concern:

Be it known that I, W. D. MAYFIELD, of Bloomington, in the county of McLean and State of Illinois, have invented a new and useful Mode of Detaching Horses from Vehicles; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing. forming part of this specification, in Which Figure 1 is a bottom View of the whifiietree. Fig. 2 is a longitudinal section of same. Fig. 3 is a view of disconnecting double inclined plane.

Similan letters denote the same part.

The nature of my invention consists in a suspended double inclined plane for moving plates from the ends of the whifiletree and thus throwing off the traces.

In the drawing A is the whiflletree, having the piece a, with double inclined panes b, suspended between jaws 0, attached to the rear of the whiflietree.

(Z (Z are the pins over which the trace loops pass; plates 6 6 attached to rods f f, held by eyes 9 9, pass over these pins, and when the trace is attached, the plate is against the end of the whifiietree, as in Fig. 2. These rods f abut against the flanges 79 Z), and move outward when the piece a is lifted by cord h. This moving outward of the rods f throws plates 6 e from the ends of the whitfletree and causes them to throw the trace clear of pins d; when the horse is detached.

I claim The swinging piece a, with flanges b as described in combination with the plates (Z d and rods f f, operating together as and for the purposes set forth.

In testimony whereof, I have hereunto signed my name before two subscribing witnesses.

W. D. MAYFIELD. Witnesses:

J. W. GRIsT, E. HUNT.
